What is the Standard Size for a Double Kitchen Sink?
Choosing the right size double sink for your needs can be difficult. While dimensions can vary, most standard double bowl sinks fall within some typical length, width, and depth ranges to provide enough space for washing dishes and preparing food.
Understanding standard double kitchen sink sizes will ensure you select the most practical model for your household and install it properly into your countertop and cabinet.
Typical Double Sink Dimensions
Length
The typical length of a double bowl kitchen sink ranges from 30 to 33 inches. This front-to-back measurement provides room for washing average-sized baking sheets or roasting pans in one basin while using the other side for dish racks or drying clean dishes.
| 30-33 inches | Standard double sink length |
| Accommodates | Large pots, pans, and dishes |
When planning your installation, make sure to measure the precise inside length of the sink's base cabinet to ensure your chosen double sink size will fit.
Width
The width of a double bowl sink can vary greatly depending on configuration, install type, and kitchen dimensions. Many equal double basin sinks come in standard 36-inch widths to perfectly fit enclosed standard sink base cabinets.
However, large farmhouse or apron-front double sinks may range up to 48 inches wide or even larger to maximize functionality. For smaller spaces, compact models around 33 inches wide allow adequate room for washing and drainage while conserving precious counter workspace.
| 33-34 inches | Compact double sink |
| 36 inches | Standard equal double basin |
| Up to 48 inches | Large apron front style |
Depth
Most standard double kitchen sinks have a depth between 8 and 10 inches which provides ample room for washing larger pots and pans. Deeper basin sinks may range from 10-12 inches, however anything deeper than 10 inches runs the risk of needing custom cabinets or alterations during install.
Take care when selecting an extra deep double basin sink that it will actually fit your existing sink base without hitting the wall or pipes behind it. An offset drain configuration can help maximize usable space in a deeper sink.
| 8-10 inches | Standard double sink depth |
| 10-12 inches | Extra deep double sinks |
Choosing the Right Sink Size
Household Size and Use
Consider how your household utilizes the kitchen sink currently and what you'd like to accomplish with an additional basin. The number of people and your daily cooking and cleaning needs should impact your double sink size selection.
For example, busy families with multiple home cooks may prioritize a larger double bowl sink for multi-tasking, like soaking pots on one side while washing veggies on the other. For a household that mainly uses the sink for quick handwashing and cleaning a few dishes, a more compact double basin style should meet needs.
Kitchen Layout and Space
The existing kitchen layout and available counter workspace may dictate how large or small your double sink realistically can be. Take measurements to determine the maximum width you have to work with based on cabinets and proximity to appliances or the kitchen triangle.
If your kitchen is limited on counter area around the sink, choose a smaller double basin sink size, around 33 inches wide, to open up landing space. Those with a more spacious kitchen can size up for a larger double bowl sink, up to 48 inches wide, for increased multi-tasking utility.
Material and Install Style
The thickness and style of your chosen sink material impacts the overall dimensions of a double bowl sink. For example, a thick, durable fireclay farmhouse apron-front sink may have slightly different external measurements than a thin stainless steel topmount sink of the same stated size.
Additionally, undermount installation removes the countertop rim increasing overall depth. Make sure to communicate your material choice and desired mounting style to accurately determine the right double kitchen sink size for your space.
Measure Carefully Before Buying
Since double sink dimensions can vary so widely, precise measurements of your countertop opening and sink cabinet are crucial before selecting a model to ensure a perfect fit. Make sure to account for the extra height of countertops and desired backsplashes as well.
Consult the product description for exact double basin sink dimensions and measurements. Consider width variations from drain placement and divider walls as well. With details in hand and clearly measured spaces, you can zero in on the ideal standard double sink size for your kitchen's needs and layout.

To recap typical dimensions:
- A 33-inch wide double basin sink allows functionality while conserving space.
